When a foehn storm hits Lake Uri (Urnersee) in Switzerland one thing is for sure: Balz Müller and his brothers are there no matter how cold it is. After one month off the water because of a little ankle surgery (Balz calls it “metal removal”) there is no reason of holding back anymore. 6 degrees water temperature and gusts over 50 knots were the perfect ingredients for a freestyle session at Lake Uri in the middle of the Swiss alps.
